Setting up a subwoofer in a home theater

The presence of a high-quality subwoofer provides reproduction of deep and clear bass. In order for acoustics to provide good sound, it is worth buying an active model of the device. Despite the fact that a passive subwoofer is cheaper, it can not provide high-quality reproduction of low frequencies. In addition to a competent choice, you should correctly install and configure the device.

Placement and connection of a subwoofer to a home theater

Some people think that you can install acoustics absolutely anywhere in the living room. However, this is not at all true. If placed improperly, there is a high probability of loss of sound quality.

REFERENCE! When buying a subwoofer, you should consider the size of the room in which the device will be installed!

In order for the acoustics to be installed correctly, several nuances must be taken into account:

1. Many put a sub in the corner of the room, because they believe that this can achieve almost perfect sound. However, this arrangement cannot provide accurate low-frequency sound, as well as high-quality pairing with the rest of the acoustics.
2. If the product is equipped with 8 small speakers, it should be placed at a distance of about one meter in front of one of the speakers. This arrangement allows you to create the illusion that the bass comes directly from the speakers. This option is ideal for small home theater systems. In this case, the sub must be installed as close to the speakers as possible. After the device has been placed, you need to adjust the volume level. You need to install it in a position so that you can clearly hear where the sound is coming from.
3. When searching for the most suitable place, you can use a little trick. To do this, turn on any musical composition with low frequencies and move the subwoofer. Depending on the location of the sub, the sound will change. This is necessary to get the perfect balance between all frequency ranges.

There are problem rooms in which acoustics sound deaf. Setting the optimum sound in them is very difficult. You can try to walk around the room with a subwoofer and listen to how it sounds. Or you can just put the product closer to an armchair or sofa.

ATTENTION! Setting up is much easier if the subwoofer works in conjunction with large speakers.

To connect any subwoofer model requires a signal and, of course, power. The most suitable outlet is responsible for providing power.

An RCA connector is used to connect to a media device. Therefore, an appropriate cable is required. One end of the cable connects to the line out on the home theater, the other to the subwoofer jack. If there is no linear connector at the cinema, then the connection is made using the terminals on the subwoofer. The right and left terminals of the external device are connected to the corresponding terminals of the subwoofer using an acoustic cable.

When connecting two audio devices, you must use the Y - shaped RCA adapter. If the adapter is not at hand, the product should be connected to the output terminals of the cinema, strictly parallel to the speakers.

ATTENTION! To ensure reliable operation of the device, as well as to prevent its possible failure, it is recommended to connect the subwoofer to a surge protector or uninterruptible power supply.

Setting up a single subwoofer

After the device is installed and connected, it needs to be configured correctly. This is done as follows:

1. The frequency adjustment knob must be set to the maximum position.
2. You need to go to the menu of the external audio device and find the subwoofer settings in it. The controls located here determine the frequency range reproduced by acoustics. Many device models range from 40 to 200 Hz. As a rule, this is indicated in the attached instructions.
3. When the recommended values ​​are not indicated, then you should focus on the size of the speakers. If they are small, then the optimal frequency will be 150-200 Hz, medium size - 80-100 Hz, large - from 60 to 80 Hz.
4. You should also correctly set the phase of the device. This is very important as it affects the sound quality. Ideal is when the low-frequency speakers of the main acoustics and subwoofer work synchronously. Otherwise, the waves begin to cancel each other, and the sound quality of the bass will be significantly reduced.

REFERENCE! Modern models of the device have an automatic switch and phase adjustment. This allows the subwoofer to independently "make" adjustments to ensure the highest quality sound.

Features setting up multiple subwoofers

Instead of a single subwoofer with high power, it is advisable to use two less powerful products. This will allow you to get the most uniform sound that will fill the entire volume of the room.

Setting up multiple subwoofers connected to the same home theater has its own nuances:

1. It is advisable to use devices of the same manufacturer or with similar parameters. This will help to avoid various problems during the setup. It is very important that the products used have the most similar characteristics. Only in this case, you can achieve the perfect sound.
2. It is required to place acoustics, observing all the recommendations. Install subwoofers in diagonally opposite ends of the room.
3. All settings of the used subs should be identical.

To get the highest quality bass, you should methodically follow all the necessary recommendations. It is also worth paying attention to the fact that two high-quality subwoofers are the best option for a home theater, as they provide sound filling the entire area of ​​the room, and also create excellent dynamics.
